Biphenyl-4,4'-diboronic acid, 94%, Thermo Scientific Chemicals

Description

Biphenyl-4,4'-diboronic acid is used in the preparation of cycloparaphenylenes through Suzuki coupling. It is also employed in the synthesis of 1,3,2-diazaboroine derivatives, which is useful for organic thin-film transistor applications. It plays an important role in the preparation of arylboronates from reactions with catechol, dihydroxynaphthalene and diaminobenzenedithiol, which finds application as organic field-effect transistors and light emitting diodes.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
